DESIGN OF JIGS & FIXTURE

INTRODUCTION FOR DESIGN OF JIGS & FIXTURE

Design of  jigs & fixture is key to effective utilization of machine tools. Basics of fixture design if not implemented correctly results in poor productivity & quality problems. Set-up time and cycle time reduction, increased accuracy on components, deskilling the job setting operation are the obvious advantages of a good fixture. Competence in right fixture differentiates excellent organizations.

A complete process of fixture design will be carried out from concept to finish design. Pre-design activities like design input, conceptualization, process planning, accuracy consideration, cycle time estimation, POKAYOKE, 3D modeling of parts and assembly. Design for Accuracy, Manufacturing and Assembly will be addressed during the course.
